Good afternoon!
The Haiku OS project (not-for-profit organization, founded in 2001)
has
found ourselves in a weird spot, we have a working Mesa software
render library based on a *heavily* modified Mesa 7.4.4.
http://cgit.haiku-os.org/haiku/tree/src/libs/mesa
However as you can imagine, updating that is going to be a *big*
pain point. As Haiku is looking to get some basic 3D rendering
going on it's cards, we need to do upgrade to a newer version of
Mesa.
If we produced well thought out Haiku OS support patches, would
Mesa as a project be interested in accepting them upstream? I think
a better direction may be to move away from the heavily custom
integrated mesa library and move to stock version.
These patches would likely start as run-of-the-mill #ifdef __HAIKU__
macros.
In general I'm happy to take patches for Haiku. But I wouldn't want
to see #ifdef __HAIKU__ lines scattered all over the code.
Hopefully,
that can be limited to header files as with other platforms.
My first work is here:
http://pub.haikufire.com/mesa/haiku-mesa-patch1.5.diff
This gets glsl, mapi/glapi, mesa, glu compiling with very few changes
in
Mesa
At this point I don't think using DRI2 is do-able as it is very Linux
oriented, however I think we may be able to get things working
(software at
least for now) by using our own external GLView within
http://cgit.haiku-os.org/haiku/tree/src/kits/opengl which simply links
to
some key Mesa libraries.
